Review of MECOS microscopy
complex utilities
Family of MECOS-C2 automated microscopy systems
includes
hardware-software complexes with different equipment and programs
compositions. Thanks to modular
architecture all types of standard microscopy techniques (bright field, dark
field, polarization, reflected, inverted, luminescent), different levels of output, automation,
image quality, multifunctionality can be offered. Variety of
properties are supported by usage of many typical well-known models of
microscopes, videocameras, motorized utilities, computers, together with
large group of functional programs for different analyses, and together with
a lot of special
and typical options such as 20x oil or dry large NA objective, motorized stages for many
glasses, special specimen holders, immersion oil dropping device, specimen
preparation tools, slide handler system, slide identification bar code
device and more.
The below article are intended for
user preferring to choice complete set himself. Just the same we recommend
read it briefly a user who doesn’t interest in technical details and is going
to book a full system through our consultation.
A microscope
choice
Modern microscopy system needs binocular
microscope with additional phototube – trinocular microscope. We offer also cost
effective models without oculars with viewing by videocamera on computer
screen only.
The MECOS system can be completed by
microscopes of many manufacturers. A microscope must include
adapter for videocamera connection (C-mount or F-mount)
with magnitude matching to censor size of videocamera. Cost effective complete set arises if a
usual microscope is completed by additional motorization
equipment of another manufacturer. The equipment can’t be integrated with a bad mechanics quality
cheep microscopes. There are examples of low boundary mechanics quality
microscopes among models of different manufacturers:
NIKON Eclipse E200; Zeiss Axiostar+; Motic BA300; Olympus BX41;
Leica DME; Meiji Techno MT4300H.
Don’t hesitate to consult us
if you are going to buy microscope for MECOS system yourself.
A computer choice
MECOS systems use PC computer
beginning from Pentium
4 Win XP. Some videocameras can demand additional standard utilities. Advanced sets
are preferred for more fast work, database size and reliability, net
connection. Resolution of display must match resolution of videocamera
used. Please don’t hesitate to consult us if you are going to buy PC
yourself.
Equipment of
motorization
choice
Equipment of motorization (automation) can consist of
the following units: motorized focus drive; motorized xy stage; motorized
objective revolver and motorized condenser; motorized filter holder;
motorized slide handler, slide bar code
identification and others. Choice of motorized equipment depends on microscope
properties and needs our consultations. For more details see
Motorization equipment
Specimen preparation tools choice
Advanced property of MECOS programs is possibility to work with hand made
specimens of blood. Hand techniques of specimen preparation
use cheap materials but have low level of standardization and are
labor intensive. Modern automated specimen preparation
devices can improve significantly labor conditions and analyses
accuracy.
We recommend to use
such devices, see Specimen preparation tools.
Specimen
preparation devices are strongly recommended fore
some techniques such as
helminth
eggs analysis.
Videocamera
choice
There are hundreds of types of videocameras for microscopy
on market. They differ by resolution, time of shooting, speed of input,
color quality, sensitivity, level of noise, controllability, live video
quality, computer interface and others.
As
quantity as quality of image pixels are important for computer analysis and
for visual analysis on a computer screen. Color 3CCD cameras
have advantage in accuracy of color transfer above 1CCD (1CMOS) cameras.
Cameras with 10 or more bits per pixel have advantage in accuracy
of brightness (dynamic range) transfer above cameras with less bits
per pixel.
The more the number of image pixels a
censor of a camera has, the less its image per second transfer speed to a computer. For
example 4 M
pixel color images can be input presently not faster then 15-20 frames per second. It
may be too slow for live object viewing or for fast automatic analysis. The more
magnification of microscope objective is used the less videocamera pixel resolution
is effective because of optical restrictions.
So the choice
of videocamera with large pixel resolution can be not best one for your
application. Please don’t hesitate to consult us if you are going to buy videocamera yourself.
